Tammy, can you hide the Conference link (on the left) from the course navigation? You can do this by gong to Settings, clicking on Navigation (tab at top of page), and dragging it down to the "hide" area.

Thanks, Kona. Is there a way to do this as an Admin so that it would apply to every course in the system? Further, once it is hidden, is there a way to disable it so that Teachers cannot add the link back to their course?

Tammy, my guess is that you might be able to hide this using some custom global javascript. Yet, that is beyond my area of expertise so I'm going to share this with the Canvas Developers group to see if they can help.
